  4. What is Java? ➢ Java was created by a team lead by James Gosling in 1995 for Sun Microsystems. ➢ Java is concurrent, class-based and object-oriented programming language ➢ Java is a platform independent programming language that follows the logic of “Write once, Run anywhere”. ` EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  10. Features of Java Feature of Java Simple Portable Object-oriented ➢ Java was designed to be easy for professional programmer to learn and use effectively. ` Secure Distributed Simple Dynamic Robust High Performance EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  11. Features of Java Feature of Java Simple Portable ➢ Applications written using Java are portable in the sense that they can be executed on any kind of computer containing any CPU or any operating system. Object-oriented ` Secure Distributed Portable Dynamic Robust High Performance EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  12. Features of Java Feature of Java Simple Portable ➢ Java is true object oriented language. ➢ Everything is considered to be an “object” and all operations are performed using these objects. Object-oriented {OOPS} {OOPS} ` Secure Distributed Object-oriented Dynamic Robust High Performance EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  13. Features of Java Feature of Java Simple Portable ➢ Java Programs run inside virtual machine sandbox to prevent any activity from untrusted sources. ➢ No use of explicit pointer. Object-oriented ` Secure Distributed Secure Dynamic Robust High Performance EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  14. Features of Java Feature of Java Simple Portable ➢ Java has a feature called Remote Method Invocation (RMI) using which a program can invoke method of another program across a network and get the output. Object-oriented ` Secure Distributed Distributed Dynamic Robust High Performance EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  15. Features of Java Feature of Java Simple Portable ➢ Java programs carry with them substantial amounts of run-time type information that is used to verify and resolve accesses to objects at run time. Object-oriented ` Secure Distributed Dynamic Dynamic Robust High Performance EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  16. Features of Java Feature of Java Simple Portable ➢ Java checks the code during the compilation time and run time also. ➢ Java completely takes care of memory allocation and releasing, which makes the Java program more robust. Object-oriented ` Secure Distributed Robust Dynamic Robust High Performance EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  17. Features of Java Feature of Java Simple Portable Object-oriented ➢ Java achieves high performance through the use of bytecode which can be easily translated into native machine code. ` Secure Distributed High Performance Dynamic Robust High Performance EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  18. Java Environment

  19. Java Environment JVM (Java Virtual Machine) is an abstract machine. It is a specification that provides runtime environment in which java bytecode can be executed. JDK JRE JRE (Java Runtime Environment) is a runtime environment which implements JVM and provides all class libraries and other files that JVM uses at runtime. Development tools ` Java Class Libraries JVM JDK(Java Development Kit) is the tool necessary to compile, document and package Java programs. The JDK completely includes JRE.

  32. Data Operators in Java 1 Arithmetic Operators 2 Unary operators ` 3 Relational operators 4 Logical Operators EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  33. Arithmetic Operators + >> 2 + 3 5 >> +2 Add two operands or unary plus - >> 3 – 1 2 >> -2 1 Arithmetic Operators Subtract two operands or unary subtract * ` Unary operators 2 >> 2 * 3 6 Multiply two operands Relational operators: 3 / Logical Operators 4 >> 6 / 3 2.0 Divide left operand with the right and result is in float % >> 5 % 3 2 Remainder of the division of left operand by the right EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  37. Functions In Java

  38. Functions in Java A function is a block of organized, reusable sets of instructions that is used to perform some related actions. ` Built-in Function Why do we use functions? ➢Re – usability of code minimizes redundancy ➢Procedural decomposition makes things organized Function User Defined Function EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  39. Functions in Java function parameters User Defined Function function definition Syntax: function return value modifier returnType methodName(parameters) { Statements… } ` Example: public static int add(int a, int b) { function call int result; result = a + b; return result; } output EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  40. Object Oriented Programming

  41. Objects ➢ Object is simply a collection of data (State) and methods (Behaviour) that act on those data. State: Color Size Shape • • • ` Behavior: Power On(); Call (); Message (); • • • EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  42. Class ➢ Class is a blueprint from with the objects are created. class Phone{ String brand; int batteryPower; String processor; . . public Phone(String phoneBrand, int power, String phoneProcessor) { brand = phoneBrand; Batterpower = power; processor = phoneProcessor; } //Other class methods ` Object 1 Object 2 } Object 4 Object 3 EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  43. Inheritance ➢Inheritance is a mechanism through which one object acquires all the properties and behaviors of parent object. Mobile Super Class ` Child Class Apple Samsung Google EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  44. Encapsulation ➢Encapsulation is the mechanism that binds together code and the data it manipulates together. ` EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  45. Polymorphism ➢Polymorphism is the ability of a variable, function or object to take on multiple forms. Mobile ` Camera Remote MP3 Player EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  46. Abstraction ➢Abstraction is the methodology of hiding the implementation details from the user and only providing the functionality to the users. ` EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training
